GUIDE FOR sEwlNG-MACHINE HEMMERS.

SPECIFICATION forming'part of Letters Patent No. 755,348, dated March 22, 1904.

Application flied March s1. isos.

T a/ZZ whom t may concern: I

Be it known that I, HENRY BLASKOPF, a citi- Zen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Guide for Sewing-Machine Hemmers, of which the following is a full, clear, and exact description.

This invention relates to an improved means for guiding and simultaneouslycurling a piece of fabric as it is drawn into a hemmer or feller so that after the fabric is once inserted into the machine the services of an attendant are not required, the .device being to this extent automatic.

This specification is an exact description of v one example of my invention,'while the claims define the actual scope thereof.

Reference is to be had to the'accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view showing the invention in use. Fig. 2 is a plan view illustrating the connection of the device to a hemmer or feller. Fig. Sis alongitudinal section on the line 3 3 of Fig. 2. Fig. 4 is an enlarged section on the line '4 4 of Fig. 2, and Fig. 5 is a fragmentary perspective view of the guide-plate.

In Fig. 1 a indicates the table or work-support of a sewing-machine, which may be of any desired form. @indicates the presser-bar, and c vthe needle-bar. In Figs. 1 and 2 d indicates a hemmer or feller of any approved construction. Ordinarily it is necessary for an attendant to stand at the machine and roll one edge of the fabric and guide it into the hemmer. My invention does'this work automatically, and it is of special value in factories where a large number of machines are in operation, and then an attendant may pass from one machine to another, applying the pieces of work as others are nished. This will dispense with a great number' of attendants, as will be apparent.

According to the embodiment here illustrated the invention comprises a base e, preferably in the form of a plate and mounted when in use as illustrated in Fig. 1. On the Serial No. 150,400. (N0 modem base e is arranged the guide-plate f, which Vhas a slot f', receiving a thumb-screw e', working in the base @,whereby the plate f may be adjusted with respect to the base. Said base is formed with two longitudinally-alined guides f2f2, these being in the form of lips struck up from the plate itself and turned over'the plate, so as to guide the edge of the fabric between the top of the plate and the under sides of the guides. On the guide-plate f is arranged the curler-body g, which' is in the form of a plate having a slot g', through which passes a thumb-screw f3, working on the guide-plate f and permitting the curler-body 1 to bel adjusted longitudinally at will transversely with respect to the guides f2. The curler-plate has the curler hingedly mounted thereon, and this comprises a shank aa curved curler proper, la', and a weight h2 at the end thereof, such parts normally lying as shown in Fig. 4 and the weight serving to keep the curler in active position, while the hinge connection between the shank h and the body g allows the curler to be thrown over into the inactive position indicated by the dotted lines in Fig. 3.

In the use of the invention the strip of fabric is placed on the guide-plate f,with its lefthand edge lying under the guides f 2. The right-hand edge of the fabric is then turned over, as indicated by the full lines d in Fig. 4 and the dotted lines c" in Fig. 3, this turned edge being placed under the curler la', after which the fabric isled into and through the hemmer in the usual manner. As the sewingmachine presses the fabricthroug'h these parts the right-hand edge ofthe fabric is automatically curled "over in position to be under the hemmer, the same as has heretofore been done yby the hand of the attendant.

curler-body, means for adjustably connecting the curler-body and plate, a curler-shank hinged to the curler-body, a ourler proper carried by the shank, anda weight attached 'to the ourler proper'.

2.' A curler-guide for sewing-machine hemmers, comprising a plate, two guides carried thereby in longitudinal alinement with each other` and lying over the plate, a curler-body lying on the plate, means for connecting the curler-body and plate to allow the eurler-body longitudinal adjustment transversely of the guides, a curler-shank hinged to the ourlerbody, and a curler proper carried by the shank and curved upward and thence downward to- I5 to this specification in the presence of two sub- 2O soribing witnesses.
